Ground glass nodular shadow is a nodular shadow in the lungs found by imaging, like ground glass, with mildly increased density, often malignant tumors, benign tumors, inflammation, interstitial lung diseases, or intrapulmonary lymph nodes.
Pulmonary ground-glass nodules are often considered as pneumonic pseudotumor, pulmonary malformation, intrapulmonary inflammation, pulmonary malignant tumor and metastatic tumor, etc. The main need is to screen for malignant neoplastic diseases, early detection and early treatment.
Pulmonary ground glass nodules are graded according to their size, morphologic features, and imaging signs of malignancy; the higher the grade of the nodule, the greater the chance of malignancy. Pure ground-glass nodules detected for the first time are recommended to be reviewed in 6-12 months, depending on the size of the nodule, to determine whether it persists, and puncture biopsy can be performed to clarify the nature of the nodule if necessary for high-risk nodules.
Therefore, it is recommended that patients seek medical attention in a timely manner so that the doctor can assess the risk level of the nodule in the light of the symptoms, imaging features, and risk factors, and actively intervene in the treatment.
